Black Widow vs. Tarantula
Video summary
Press to jump
- 0:36Custom glass enclosures with dirt and sticks are set up for both spiders.
- 1:55Time-lapse contrasts the tarantula's thick silk carpet with the widow's near-invisible sticky strands.
- 4:00A black widow egg sac appears overnight, followed by macro footage of how females make them.
- 9:14Dusky cave roaches: the tarantula pounces, while the widow bites, envenomates and wraps its prey.
- 11:17A tiny male black widow enters the female's tank and is knocked away.
- 12:55The bare-hand handling test begins with a heart-rate monitor; the black widow's turn comes at 15:18.
Which is scarier to hold, a tarantula or a black widow? TerraGreen settled it with a heart-rate monitor strapped on. With the black widow on his hand, his pulse peaked at 163 beats per minute, well above where the tarantula had taken it. The description admits the video was not fun to record.
That test closes "Black Widow vs. Tarantula," which drew about 1.2 million views since yesterday. Despite the title, nobody fights. As with the channel's "1,000 Ants vs. Challenges" and its slime mold obstacle course, the "vs." means a side-by-side experiment. A greenbottle blue tarantula and a black widow, each in its own glass tank, go through the same tests.
The homes come first. In time-lapse, the tarantula smothers its enclosure in thick silk, while the widow strings up nearly invisible, sticky threads. Then the widow goes off script. "That is a black widow egg sac that literally wasn't there last night," he says, and the video pauses for macro footage of how females make and wrap them.
The hunting rounds bring out the difference. Both spiders snatch crickets quickly. With large dusky cave roaches, though, the tarantula simply pounces, while the widow bites, injects venom and wraps its catch. He describes that venom as 15 times more potent than a rattlesnake's. A tiny male widow dropped into the female's tank gets knocked away rather than eaten.
The handling section is where the comments pile up. The widow falls from his hand partway through and is recaptured safely. His scream at that moment is the one viewers keep timestamping, and some say they screamed along. A few confess they clicked expecting Scarlett Johansson. Others are busy suggesting which creatures he should compare next, including one viewer's repeated plea for 100 moths and a single light.
When he gets back to the tank, the black widow is laying a second egg sac.
